Thanks Cadidog. Funnily enough I was told they got him as a pup from a farm in North Wales. It's good to have someone validate my experiences
we had GSDs and Springers growing up, I took care of their walks and training as a teen, and although I logically knew what I was taking on in a collie, the emotional reality is so intense, sometimes I wonder if it's just my collie, or just me!
I don't really think so though. I think I've might have the epitome of the breed, the quiddity of collies, and others aren't quite so intense. He's sooo intelligent, has personality enough for 2.5 dogs, and is so terribly, absolutely in need of things to do. He's relentlessly collie.
That's the thing with them, OP. Your friend might get a, I hesitate to say chilled, because no collie is chilled, but a relatively laid back collie. I hear some people have had those! The trouble is, your friend might get one who does what is says on the tin.
They are bred to fixate on one person, and be tuned in to that person, and react when that person moves. My son can't go for a sudden wee without the collie dancing and singing - if the boy leaves it a bit too late, and is squirming and rushing, the collie reacts. I've trained him to 'watch me', and he tries, oh god he tries, but he's so torn. He has an imperative to watch the boy too! His job is to mind the smaller ones!!!
Fortunately my son's been around many dogs all his life (miniature Schnauzers are fairly bombproof, if yappy, as it happens) and we've been through the whys and wherefores of this behaviour, and so he does a swift walk with eyes down, arms by his side, resolutely ignoring the collie, but he's ten, and big for his age - an unknowing, unwary small child? I shudder to think.
Collies are bred to think, and work. They will work until they drop. They will think on their feet, even when you really don't want them to, because they were bred for the field, where they'd often have to decide stuff on their own, out of sight/earshot of the handler, especially in the hills.
None of that's good for a house, really, and that's why there are very many collies in rescues. Collies can be pets, oh yes, they most certainly can, if you are prepared to constantly manage their work
